如何在与preg_match匹配后获取变量值

This is my code:

$str = "nbvmxnbvn Shopify.shop=gfkhfhkd";
preg_match('/Shopify.shop=/', $str, $matches);
print_r($matches);

I'm getting the output after print_r as Shopify.shop= but I want gfkhfhkd as the output.

Modify your regex slightly so that it can capture the proper substring you're looking for.

preg_match('/Shopify.shop=(.*)/',$str,$matches);
echo $matches[1];   //gfkhfhkd

Fiddle

$matches = preg_grep('/Shopify.shop=(.*)/', $str);
print_r ($matches);
